EDWARD KAY, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR OF ONE- HALF TO SAMUEL BESVVIGK, OF SAME PLACE.

LUBRICATOR FOR ECCENTRICS.

BFEC'IFICATION forming part of Letters Patent No. 317,372, dated May 5, 1885.

Application filed April 6, 1885. (No model.)

To all whom it may concern.-

Be it known that I, EDWARD KAY, a citizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented certain Improvements in Lubricating Eccentrics, of which the following is aspecification.

My invention relates to that class of eccentrics which carry a supply of oil or lubricating material, one object of my invention being to permit ready access to the lubricating-chamber, and another object being to insure the proper application of the lubricating material to the surface of the eccentric. In the accompanying drawings, Figure l is a vertical section, partly in elevation, of a lubricating eccentric constructed in accordance with my invention; Fig. 2, a plan View of the same, and Fig. 3 a perspective view of part of the strap.

A is a shaft, on which is an eccentric, B, of the usual construction, the eccentric-strap consisting of two segments, D and F, the former being secured to or forming part of the eccentric-rod G. The other or outer segment, F, has a box or receptacle, J, which may be secured to the segment or may be cast therewith, the latter construction being shown in the drawings. This box has a hinged lid or cover, a, so that ready access can be had to the interior of the boX at any time for the purpose of replenishing the same with lubricating material or for other purposes. This lid has around the edge a flange, b, which, when thelid is closed, overlaps the sides of the box and serves to make a close joint and prevent the splashing of any of the lubricating material from the box. The lubricating material gains access to the surface of the eccentric through an opening, d, in the strap F, and to permit the application of the lubricant to all portions of the surface of the eccentric a groove, f, is formed in the inner face of the strap, said groove communicating with the opening (I,

and in order to insure the proper discharge of the lubricant, the groove is inclined obliquely, as shown in Fig. 3, it having been found that such inclined groove is most effective for the purpose intended.

The lid of the box or receptacle J may be removable, instead. of being hinged; but the hinged lid is preferred.

I claim as my invention- 1. The combination of an eccentric strap with a boX or receptacle carried by the strap communicating with the inner face thereof and having a hinged or removable lid or cover, as set forth.

2. The combination of the eccentricstrap having in the inner face an oblique groove or channel, f, with a box or receptacle communicating with said oblique groove, as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

EDXVARD KAY.
